To all whomit may concern: I Be it known that I, ALVAH B SHNEIQL, J r., a citizen of the United States, residing at Philadelphia, county -'of Philadelphia and s State of Pennsylvania, have invented certain new and useful Improvements in Envelops the Like, of which the following is a speci v fication. in My invention relates to a new and useful improvement in envelops for filing or carrying correspondence and the like, and has for its "object to primarily so construct such an envelop that the end gussets will expand reater, at the top than at the bottom thus acilitati'ng the envelop. v

' A furtherobjectof my invention is to so secure a tape between the layers of the back of the envelop as tov prevent it from pulling out or having a tendency to tear the outer layer and a still further object of my invention' is to provide for the separation-0f the pocket of the envelop by a leaf or leaves, or partition or partitionswhich are free to swing back and forth within the pocket in accommodating the contents thereof,

With these ends in view this invention consists in the details of construction and] I combination of elements hereinafter set forth and then specifically designated by.=

the claims.

'SIn order tha ithose skilled the at to 4 which this invention appertains ma under- -.st andilio w to make and use the'samc l will describe its construction; in detail, referring by letter-to the accompanying drawing forming a partio-fthis specification in which Figure 1,. is a perspective of an envelop 4o 'inade in accordance withiny improvement:

I'Fig; cross section atthe back showing v. th'e manner of running the tape therein. Fig. 3, perspective showing the envelop partly completed; i Fig. A, a vsimilar view showinga com'pletedenvelop of one style.

' AFig. 5, represents a scored and'bent gusset 7 re being applied to the envelop. Fig. 6,. a perspective of the gussetafter it is folded into the position adapted for entering -into the constructing of the envelop. r

In carrying outmy lnventlon as shown in:

Figs. 1; to' 6 inclusive, I form an expan'sible envelop with a front sectionA-"andlback sec-' tion Bthe'twq being connected-by the'gusset v G which latter consists of asingle' piec of envelop. for Carrying or Filing Correspondenceand the inspectionv of the" contents of 1 material scored .as shown in Fig. fi' havi ng the V-shaped cutaway portions D, and when this gusset is foldedasshown in Fig. 6 and.

,attached tothe front and back sections it forms the bottom and endsections of the The front and back sections areeach com posed of two layers of materialand in buildnig up the envelop the gusset is pasted to the inner layers of each of these sections,

and to accomplish this the gusset isprovided with the inturnc'd ends a and b, the ends a being pasted upon, the outer surfaces and I along the end edges .of the sections A and B while the ends-f) are likewise pasted upon the outer surfaces along the bottom edges of said sections. r

In order thatthe pocket of the'envelop mayfhave agreater expansion at the to than at the bottom one or more of the folds the bottomby the front end I; in pasting the upon each end of the gusset is confined at latter in the front section; this will limit 1 the bottom of the envelop to an expansion less than the expansion at the top, accord- 111g to the amount confined by the front end 6, while the top will be free to expand the full wldth of thegussetthus producing a very desirable result namely, permitting the free -access to the top of the pocket'of the envelop and the .easy examination of the a contents thereof, without the necessity of removal. YVhile the allowance for the extra amount of expansion at'the top could be made at either the front or back or at both,

it will generally suffice to have it adjacent to the front of the envelop, as the usual de.

sire isyto .tilt the front forward to examine the contents. To complete the envelop a layer ofmaterial is pasted uponthe outer surface of both the front and back sections,

-' thereby covering the ends of the gusset and strengthening -the front and back sections.

In order'that the envelop may be tied upfor filing away, itis advantageousto permanently attach a tape thereto but-heretofore the attachment of-such a tape has been of such a character as to render it liable to be pulled off or to tear the envelop, this I overcomeby slotting the outer layer of,ma- 'terial ofthe back section as indicated at d and 'e and passing the tape E through these slots so that when the outer layer is pasted to the back section the ends of the tape will project so as to utilize for tying up the envelop. By .thus extending the tape entirely section, its ends projecting for tying up the through the back section it cannot be readily pulled out andthe tendency to tear the en velop is eliminated.

- As shown in Fig. l the back section may extend'so as to form the flap Gr oras shown in Figs. 3 and a this extended flap may be omitted and the upper portion of the back may be utilized as a flap for folding down over the front section, and also the outer layer of the front section may be extended so as to form a secondary flap H adapted to fold down upon the face of the envelop.

Of course I do not Wish to be limited to the exact details of construction here shown as these may be varied Within certain limits Without departing from the spirit of my invention. Having thus fully described my invention, What I claim'as new and useful is- 1. An envelop consisting of gusset portions havin inturned edges, said edges being pasted between tWo layers of the front v and back sectionsof the envelop, and a tape passed through the outer layer of he back envelop, as specified.

2. In an envelop, a front section, a back section, both of said sections being composed of two layers of material pasted together, a gusset folded so as to form the bottom and ends of the envelop, inturned ends formed upon the gusset, said gusset being so pasted between the layers of the 'front and back sections as to confine one or more folds of said gusset at the bottom of the. pocket, as and for the purpose set forth.

3. In an envelop of the character described, a back section formed of two layers and a tape passed through slots in the outer layer,the ends of said tape issuing in opposite directions and both being extended as and for the purpose set forth.

In testimony whereof, I have hereunto affixed my signature in the presence of two subscribing ivitne sses. I
